Hackers linked to the loosely organized Anonymous hackers group said at the beginning of the year they had stolen the email correspondence of some 100 of the firm's employees. The group said it planned to publish the data so the public would know the "truth" about Stratfor operations.
Stratfor describes itself as a subscription-based publisher of geopolitical analysis with an intelligence-based approach to gathering information.
WikiLeaks and Anonymous maintain the emails will expose dark secrets about the company. Stratfor said in its statement it had worked hard to build "good sources" in many countries, "as any publisher of global geopolitical analysis would do."
In December, hackers broke into Stratfor's data systems and stole a large number of company emails.
WikiLeaks founder Julian Assange told Reuters: "Here we have a private intelligence firm, relying on informants from the U.S. government, foreign intelligence agencies with questionable reputations and journalists."
"What is of grave concern is that the targets of this scrutiny are, among others, activist organizations fighting for a just cause."
Friedman, the chief executive, said on Jan. 11 the thieves would be hard pressed to find anything significant in the stolen emails.
"God knows what a hundred employees writing endless emails might say that is embarrassing, stupid or subject to misinterpretation. ... As they search our emails for signs of a vast conspiracy, they will be disappointed."
People linked to Anonymous took credit for the data theft. "Congrats on the amazing partnership between #Anonymous and #WikiLeaks to make all 5 million mails public," AnonSec Tweeted. AnonSec is one of several Twitter accounts used to promote and organize activities associated with Anonymous.
